You are kidding right? Carriers are tough SOBs. Even target ones are almost impossible to put under. They are huge honey combs of watertight compartments.
Yes, they are hard to sink. But if a carrier can’t make speed, or its catapaults or elevators go down its a “mission kill”. If she goes dead too far from home, your own ships will be sinking her as happened more than a couple times in WW2.
